When is it okay for a man to hit a woman?

Sup, Khoi. Some chick willingly gave you herpes. Your plantain is forever tainted. You'll never be able to experience the joys of unprotected sex ever again. (Unless you wish to pass it along as well.) You're telling me you wouldn't rough her up?

I'm not saying I'd hit a woman because she forgot to cook me dinner, but there is a line that can be crossed.

At least someone's realistic here, even though I like to deny it, I'd be mad.
I've never been in a situation like that, so I couldn't say how I'd act, honestly.
